Our movie featuring Royal College of Art graduate Julian Melchiorri's synthetic biological leaf (top) is the most watched Dezeen and MINI Frontiers video – and the most popular movie ever published on Dezeen – clocking up over 700,000 plays.

The artificial leaf absorbs water and carbon dioxide to produce oxygen, just like a plant, which Melchiorri claims could enable long-distance space travel in future.

Following close behind is our exclusive video interview with musician Imogen Heap, in which she demonstrates her Mi.Mu music-making gloves. The gloves allow her to interact with her computer remotely via hand gestures, which she claims could "change the way we make music."

Roosegaarde had just got hold of his first sample of a bioluminescent house plant, which he was unable to get delivered to his Rotterdam studio because of strict EU regulations around the use of genetically modified plants.

Rounding off the top five is a movie about using drones in the construction industry. Architect Ammar Mirjan explained how drones with cable dispensers attached could be used to quickly weave tensile structures over a void.

Launched in February 2014, Dezeen and MINI Frontiers was a major content collaboration between Dezeen and MINI, which explored how design and technology are coming together to shape the future.

Through a series of exclusive movies and a major London exhibition (above), we investigated exciting developments in emerging fields such as wearable technology and synthetic biology as well as looking at how technology is transforming disciplines including transport, fashion, music and architecture.
